Application filed August 14, 1316. Serial No. 114,877.

To all whom it may concern: v

Be it known that I, MARVIN SMITHEY, a citizen of the United States, anda resident of Lawrenceville, in the county of `runswick and State ofVirginia, have invented certain new and useful Improvements in Meters g,and'they consist in the combinations, constructions, and arrangementshereinafter described and claimed.

An object" of the invention is to provide a simple form of meter, inwhich a speedometer is combined with a number of odometers, eachodometer being adapted to register the mileage of a particular portionof the vehicle, such as a particular tire.

A further object of my invention is to the type mentioned, which has fewparts and which is cheap to manufacture, and which will not easily getout of order.

A further object of my invention is to provide ardevice comprising aplurality of odometers with. a single means for driving the odometers insuccession.

Other objects and advantages will appear in the following specificationand the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming a partof this specification, inwhich;

Figure 1l is a perspective view showing the device in positionon a car;

Fig. 2 is a face View of the device, showing certain parts in section;

Fig. 3 is a diagrammatic view showing the development'of the drum which.bears the odometers;

Fig. e is a section along the line ff-fi of Fig. 2; v

Fig. 5 is a section along the line tim-5 of Figf'is a section throughthe end of one of the odometer shafts showing the shiftable star wheels;and Y Fig. "I is a perspective view of a means for shifting any of thestar wheels.

In' carrying out my invention, l provide a casing 1 which is preferablycircular as shown in the drawings. The cover for this carrying a plateof glass 3. The ring is rotatable on the'casing, being held in position.by means of cleats or similar guide members et.

The casing 1 is provided with an extension 1x which forms a housing fora pair of bevel gears 5 and G, respectively, the former being on .the'end of ,the stub 4winch the meter may be connectcd-withfa movable partof the vehicle such as the wheel, the stub shaft also bearing a worm 8arranged to engage a worm wheel 9 disposed within the housing at the endof the shaft 10.

As will be seen from Fig. 4, theshaf-tflO isvprovi'ded with a worm 11 atits opposite end whiclrengages a worm wheel 12 on a shaft 13 bearing aworm `141in engagement with the worm wheel 15 ona shaft 16. The shaft 16bears a gear 17 arranged toengage ,an internal gear 18 on the interiorof a revoluble sleeve 19, one end `of which is jour- Ishaft 7 by meansof' naled in a partition 20, theother end fitting over an inwardly torotate thereon, the sleeve 21 beingsecured to the casing 1.

The partition 20 is part of a dru1n22 and has a portiony22 providedwith' an extension"l having a gear ring 225', the latter beinginengagement with a gear ring 23 carried by the annular plate 2i 'securedto the'ring 2. The opposite end 26 of the drum isrotatably projectingsleeve 21 so as Y supported on rollers 2T, see Figo, vcarried by thepartition 2S.

Disposed between the partition 20 and the end of the drum22 is a seriesof odometers,

while another series is disposed between the partition 20 and the end2G. y'l"neseodoni.`

into which a portion of the spring may enter thereby7 holding the wheelin position. v

Keyed to one end of the sleeve 19` is a col- -v lar 34C which isprovided with a lug or'outwardly extending finger 35 disposed in thepath ofthe star wheel when the latter is out of position, z'. e. thatshown in Fig. G. The end of .each of the odometer shafts 32 is providedwith a clutch member 32c arranged to engage a correspondingclutchmernber 36, on the end of 'a shaft 36 which is held normally inits outer portion bylgneans of a spring 37.. Each of the. star wheels 31is adapted to be shifted by means of `a device,

shown in Fig. 7. i In this ligure, it will be seen that I haveprovided aslidable shaft 40 Wheel between them, While at the same time`constructed so as to permit the normal utlon of the drum carrying thestar bein rev wheels lWithout engagement of the star wheels with theplate.

Referring. now to Figs. 4 and 6, it will be seen that'the bevel gear 6is on the end of the shaft 25 which extends through the partition28,'the end of the shaft being-provided with a split ring magnet 46arranged to operate on a Wheel 47 having a hub 48 upon which the magnetexerts a magnetic drag When the device is in operation. The wheel 47 ismounted on a bracket 49 'secured to a casing lof the device.

From the foregoing description of the various parts, the operationthereof 'will be readily understood. The instrument is at' tached in theordinary manner to a flexible transmission. The rotation of the shaft 45causes the operation of the speedometer in a Well known manner. Rotationof the shaft 1.0 causes rotationl of the sleeve 19, through the mediumof members 11 'to 18, inclusive. This carries around with it the lug 35on the collar 34' and this lug engaging the star Wheels lin succession,vturns them and thus yoperates the odometers. These odometers as hasbeen said before pertain to particular features of the vehicle, such asparticular tires. If it is desired to bring any odometer into readingposition, that is to say before the opening 50 in the top plate 51. thenthe ring 2 is grasped and turned. The drum bearing the odometers will beturned through the engagement of the gears 23' and 25 so as to bring thedesired odometer into read,- ing position. By pushing inwardly 'on the`thumb wheel 52 on the end of theshaft 36, the cup members 32c and 36 arebrought together ,so as to permit the resetting of the odometer. If nowit is desired to putrany odometer out of operative relation with f therest of the mechanism then the handle 41 vis manipulated so as to bringthe plates 42 vand 43 on opposite sides of the particular .si starfwheel., when by pushing inwardly the "wheel may be moved from theposition shown in Fig 6 to that shown in dotted lines in""Fig. 4., thespring entering the notch 3.2Y, ,see Fig. v6, so as to retain the starwheel in a fixed position, in which position it will not be engaged bythe actuating lug 35. It is only vnecessary to reversethis process bypulling the star Wheel forward into its normal position in order to putit into operac parametrica vyiththe rest of the machine. The devicerequires comparatively.

as a gear, a Geneva movement, or any other Wheel which has one or moreteeth by means of which it may be positively actuated.
